MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented Dec. 19, 1911.

Application filed December 22, 1910. Serial No. 598,765.

To all whom it may concern:

Be it known that I, .LEROY A. SANDOE, a citizen of the United States,residing at Hope, in the county of Hempstead and State of Arkansas, haveinvented a new and useful Music-Leaf Turner, of which the following is aspecification.

This invention relates to music leaf turners, one of its objects beingto provide a device of this character including a backing which alsoconstitutes means for engaging and holding each sheet or leaf at theinner edge or fold thereof, whereby the leaves will be securely heldduring the turning operation, without, however, necessitating theemployment of any intricate securing means.

A further object is to provide improved means whereby the leaves can besuccessively turned by the person using the same, there being a novelarrangement of keys designed to facilitate the turning of the leaves.

A further object is to provide a music leaf turner which can be readilyplaced upon an ordinary music rack or ledge.

WVith the foregoing and other objects in view which will appear as thedescription roceeds, the invention resides in the com- Eination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings, the preferred form of the invention hasbeen shown.

In said drawings :Figure 1 is a erspective view of the music leafturner, Fig. 2 is a transverse section therethrou h. Fig. 3 is anenlarged horizontal section t rough the meeting portions of the twosections of the backing and showing said sections swung relative to eachother so as to receive the folds of sheet music between them. Fig. 4 isa detail View of one of the trunnions used in connection with thebacking. Fig. 5 is a perspective view of the lower portion of one of theleaf turning members. Fig. 6 is a erspective view of portions ofmodified forms of leaf turning members. Fig. 7 is a section through aportion of a modified form of backing.

Referring to the fi res by characters of reference 1 and 2 designatebacking sections hingedly connected as at 3 and having cleats 4 securedalong the meeting edges thereof .1 and 2 are t and upon the front facesof the sections, these cleats cooperating to form jaws designed, whenthe sections 1 and 2 are brought substantially in alinement, to clampupon any leaves which may be inserted between the adjacent portions ofthe sections 1 and 2 and between the cleats 4. Legs 5 extend downwardlyfrom the outer corner ortions of the sections and terminate in hoo s 6designed to bear on a music rack or ledge and thus support the backingsections 1 and 2 at desired angles relative to the horizontal.

A plate 7 is secured to the back face of one of the sections 1 and 2adjacent the top and the bottom thereof, each of these plates having atrunnion 8 projecting from it and one of the trunnions being extendedupwardly from the backing while the other trunnion is extendeddownwardly therefrom, the two trunnions being disposed in alinement.Each trunnion has a head 9 at its free end, this head being preferablyin the form of a nut such as shown.

A series of sleeves 10 is mounted for rotation upon each of thetrunnions and about the same axis as the hinged connections between thebacking sections, each sleeve being secured to an arm 11 forming one endportion of a leaf turning frame 12. These frames are preferably nestedone within the other as shown in Fig. 1, the arms 11 of the outermostframe being attached to the upper and lower sleeves 10 on the upper andlower trunnions 8, respectively, while the arms of the innermost frameare attached to the sleeves which are disposed nearest to the backing.The free ends of the arms 11 project past the sleeves 10 and haveoperating devices in the form of knobs or keys 13 secured thereto orformed thereon. The intermediate portion of each frame 12 has an eye 14or the like to which is connected an elastic 15, this elastic carrying aclip 16.

In using the device, the sections 1 and 2 are swung backwardly relativeto each other so as to permit the inner edges or folds of the sheetmusic to be inserted between the cleats 4. The sections 1 and 2 are thenbrought back into the same plane, or as near thereto as possible, andthe hooks 6 placed on a supportingl ledge or the like. Sections uspermitted to lean back against a supportin structure, such as a musicrack, or the out anel of a piano, and it will be apparent t at theweight of the attachment as well as the weight of the sheet musicsupported thereby, Wlll tend to cause the cleats 4: to more firmly bindupon the sleeves. After the leaves have thus been assembled relative tothe backing sections, they are placed in engagement with the clips 16,it being possible, by means of the elastic between the clips and theframes 12, to move said clips inwardly so as to engage the edge portionsof small as well as large sheets of music. As the elastics exert aconstant pull upon the clips, it will be apparent that the leavesengaged by the clips will be held taut under all conditions.

After the various leaves have been engaged by the clips, the frames 12are swung to the right of the operator and when it is desired to turnthe first sheet of music, the lowermost one of the series of ke s 13arranged under the backing, is pres ed backwardly so as to cause itsframe 12 to swing about the trunnions 8 thus carrying the first sheet tothe left of the operator. This operation can be repeated whenever it isdesired to turn the succeeding pages. To turn back any page which hasalready been shifted to the left, it is merely necessary to push backthe key belonging to the frame to e returned.

Instead of arranging the keys upon the ends of the arms 11, and as shownin Figs. 1, 2 and 5, finger pieces 17 may be attached to said arms atpoints between the trunnions and the upstanding portions of the frame,as shown in Fig. 6. When these finger pieces are employed, they arepreferably arranged at different distances from the sleeves 10 so thatone of them will not lap any of the adjoining ones.

If desired, and as indicated in Fig. 7, the backing may be made up oftwo hingedly connected members 2 the meeting portions of which areformed with outstanding flanges 4 constituting sheet gripping jaws.

As shown in Fig. 6, the finger pieces 17 are all extended downwardl sothat their lower ends will lie in ractlcally the same horizontal plane,thus acilitating the turning of one or more pages at a time.

What is claimed is 1. A music leaf turner including backing members,hinges secured upon the rear faces thereof and constituting the soleconnection between said members, trunnions extending upwardly anddownwardly from the backing members and alining with the axes of thehinges, nested leaf turning frames ivotally mounted upon the trunnions,an an operating device connected to each of said frames.

2. A music leaf turner including backing members normally contactingthroughout the length of their inner edges, hinge connections betweensaid members, the axes of said connections bein located beyond the backfaces of the mem ers, said inner edges of the members constitutin jawsfor gripping leaves at the folds t ereof, and leaf turning devicespivotally connected to the backing members and movable about and mountedon the same axis as the connections.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
